I haven't done this in a long time, but I thought only the cycbuff, not
the metacycbuff, was noted in the storage API tokens.  So I think you can
just move the buffers to a different metacycbuff and restart INN and
things will Just Work.

Yeah, looking at the CNFS code, I think that's correct.

I don't see any reason why you'd have permission issues, since INN is
currently writing to all of those buffers anyway.
